How to Install the app twice without interference in android?

also change the package name in gradle script build.gradle module it will work

defaultConfig {
    applicationId "com.me.mesurvey" //put your package name here//
    minSdkVersion 14
    targetSdkVersion 19
}

Well it worked on other device with more recent platform ! Anyway the proper response will be you just have to change the name and the package of the application.

EDIT 1: Now if you are using Android Studio use applicationIdSuffix to have one app for each flavor.

debug {
        applicationIdSuffix ".debug"
    }
